Does anybody know of a European home security system (just a simple siren and motion sensor and an app) for when you’re away from home?
I’ve checked out Philips Hue but I still cannot tell whether they offer a normal alarm system or not.
It also seems like a lot of companies in this area have gone broke or stopped shipping.
If you have an old bell built into the door you can hook the old button up to anything like an esp32, and if you don’t and therefore need to put a wireless button on the door (like a battery operated ring) you can do the same with an esp32 plus a battery.
You could probably even buy any random old wireless doorbell and make it ‘smart’ by reading the output of the speaker unit.
On top of that, putting a camera through the peephole if available is also much easier than one would guess.
